$55 per gallon. 1 gallon covers 100sqft. What is the price per sqft?
marta [7]

the price is 0.55$ per square foot

Step-by-step explanation:

We can solve the problem by using the rule of three.

In fact, we know that:

1 gallon covers an area of 100 ft^2

While the price per gallon is

$55 per gallon

This means that the price per 100 ft^2 is $55, since 1 gallon cover 100 ft^2

Therefore, to find the price per square foot, we can write

\frac{55}{100}=\frac{x}{1}

WHere x is the price per square foot. Solving for x,

x=\frac{55}{100}=0.55\$

So, the price is 0.55$ per square foot.

Which of the following is a factor of 24x6 − 1029y3?
amid [387]

Answer:

The answer to your question is only the second and the third are factors.

Step-by-step explanation:

Find the factors of               24x⁶ − 1029y³

First find the prime factors of 24 and 1029

  24  2                1029 3

  12   2                  343 7                  Then 24 = 2³3

   6   2                    49  7                         1029 = 7³ 3

   3   3                       7  7

   1                             1

     x⁶ = (x²)³                  y³ = y³

Then

                                  2³3(x²)³  -  7³ 3  y³

Factor 3                    3[  2³(x²)³  -  7³ y³]

Factor                      3 [ (2x² - 7y)(4x⁴ + 14x²y + 49y²)]

Then

24

2x2 + 7y

4x4 + 14x2y + 49y2

All of the above
